An engine fuel injector includes an internal fuel passage in which pressure waves can develop upon opening and closing of an injection valve. A fuel pressure damper is associated with the fuel passage and operates to vary the internal volume of the fuel passage in a manner to reduce the amplitude of pressure variations and pressure waves in the fuel passage. A variety of fuel pressure damper embodiments are disclosed.

A spring clip assembly for connecting a fuel injector to a fuel rail in an internal combustion engine comprises a substantially circular ring having a circumferential outer surface, to which are attached a first and a second plurality of elongate fingers. The first plurality of elongate fingers extends in a first direction parallel to the axis of the ring and includes connecting means for attaching the ring to a fuel injector. The second plurality of elongate fingers extends in a second, opposite axial direction and includes connecting means for attaching the ring to the fuel rail. The spring clip assembly further comprises spring means held proximate a surface of the ring by either the first plurality or the second plurality of elongate fingers. The spring means provides a compressive load between the fuel injector and the fuel rail. A fuel rail-injector assembly comprises a fuel rail, a plurality of fuel injectors, and a corresponding plurality of the just-described spring clip assemblies for connecting the injectors to the rail.
